To all whom it may concem:

Be it known that I, ADOLF Roszxowsm, a subject of Russia, residing atNew York, county of New York, and State of New Yor have invented certainnew and useful Improvements in Compressors, of which the following is afull, clear, and exact description. This invention relates to animprovement in automatic air compressor apparatus, designatedparticularly for use with an im proved compressed air supply system forrailroad stations forming the'subject matter of Patent No. 1,240,373issued to me Se tember 18, 1917.

riefly, such system comprises reservoirs containin water and compressedair located beneath t 1e surface of the ground at the water station, thereservoirs being connected with each other, with a more or less remotepump stationfor the supply of water and air to such reservoirs, an witha standpipe outlet from which the water is withdrawn for use. Aparticular valve arrangement between the reservoirs, supply and servicepipes renders the system self distributing and self regulating.

The system contemplates the continued use ofthe compressed air of thereservoirs, that is the use of such air as a motive force for the waterto a low limit of pressure of such air and the restoration of themaximum air pressure through an additional supply of water from the pumpstation.

In the practical use of such system, however, it has been found thatthere is a distinct but slow dissolution of the compressed air in thewater, and as such is lost for effective uses, it must be compensatedfor, preferably by replacement. a. The present invention is designed topro vide an apparatus for the automatic replacement of such dissolved orabsorbed portion of the compressed air, and in more specific detailcomprises two comparatively small tanks preferably located at or nearthe pump station of the system and on a level below that of thereservoirs. Two-way valves, con

nected for simultaneous but reverse action, are provided, either servingto connect a particular tank with the water pipe from the reservoir andair pipe thereto, while the other at the same time connects the othertank, at both inlet and outlet with the atmosphere. The reservoirconnected tank,

which by a previous position of the valve incident to the difference inlevel, 'and the contained air forced into the system. The other tank,which in the previous position of the valves has gradually filled withwater from the reservoirs in forcing the air therefrom into the system,is the present position of the valves, open to the atmos here, drainingit of water and, of course, llingit with air under atmospheric pressureto be forced into the system when the valves are reversed.

In the drawings:

Fig. 1 is a view illustrating more or less diagrammatically the improvedcompressor apparatus.

Fig. 2 is a section of the valve.

The improved construction com rises two air receiving tanks, 1 and 2,pref rably located near the pump station A of the'im-. proved system,and on a level below the water storage or service reservoirs B of suchsystem to provide a head of water from the service reservoirs to thetanks. through the pipe 3, leading from such ser ice reservoirs.

An air supply pipe 4 leads to the air pressure pipe 4"I'or serving thereservoirs, and this pipe has a valve 5 which opens toward thereservoirs.

Tank'l has an air pipe 6 opening therefrom near the top with awaterexcluding valve 7 at the entrant end thereof, and also a water pipe8 opening therefrom near the bottom; while tank 2 has exactly similarThe respective valve casings 17 and 18,

are each provided with a port 19, lead,ing

to the atmosphere, the casing 17 or valve 12 having ports 20 and 21 forthe connect ing thereto of the air pipes 6 and 9 of the respectivetanks, and another 'port 22 for the connection of the air supply pipe 4.The

casing 18 of valve 13 has similar orts, that is ports 23, 24 forconnection of t e respective water pipes 8 and 11 of the tanks 1 and 2,and a port 25 to which the pipe 3 is connected.

The passages 14 and 15 of the valves are so relatively disposed that inone pos tion for example that illustrated in the drawings, the air andwater pipes of tank are open to the atmosphere, and hence th1s tank ischarged with air under atmospheric pressure. The air and water pipes oftank 2, however, are in this position of the valves connected with thewater pipe 3 and air supply pipe 4 of the system. The water under thehead described, will force the an from tank into the system to replenishthe absorbed air. stantially filled with water, as may be 1nd1- cated asan external gage 26, the valves are operated bymeans 16 to reverse them,utilizing tank 1 as the serv1ce tank, and opening tank 2 to theatmosphere for drainage of the water therefrom and replacement of suchwater with air for charging purposes on the next operation of thevalves. v

Beyond the mere change of the valves, the compressor apparatus isentirely automatic in its operation, and will effectively maintain a,constant air' volume in the system.

It is obvious that the invention is not limited to the use of twoairtanks, but is applicable to. the use of one or more air tanksdepending on the needs of the system. If but one tank, such as tank 1,only be required, the ports 21 and 24 of valve casings 17 and 18 can beomitted. The controlling mechanism can be operated to simply disconnecttank 1 from the water pressure ipe 3 and the air supply 4,. while thetanis vented to atmosphere and drained. This arrangement is shown inFig. 1. Then the valves 12 and 13 can be turned simultaneously todisconnect the tank 1 from atmosphere and to connect the tank 1 with thewater pressure pipe 3 and the air pipe 4. After air in tank 1 has beenforced by direct "contact with water from the water pressure pipe 3 intothe storage reservoirs B, the valves 12 and 13 can be returned tothepositions shown in Fig. 1 in order that the tank 1 may receive air,awaiting the time when again necessary to supply air to the storagereservoir.

In other words, there are certain features of the invention whichare'presentregardless of whether one or a p urality of .air tanks areemployed. Considering the operations performed by the. controllingmechanism in cooperation with an one of the tanks, the inventionprovides air charging apparatus which can be rendered operative tointroduce air into the water system while the connection between thepump and When tank 2 has become subwater reservoir is maintained. Theair is forced from a tank into the water system by direct contact with abody of water under pressure thereb reducing the number of moving partsto t e minimum. The valve mechanism is controlled by a single manuallyoperable member which, in one position, causes a tank to be drained andfilledwith air and, in another position, causes the tank to be connectedwith the water system.

While the form of mechanism herein shown and described constitutes apreferred embodiment of one form of invention, it is to be understoodthat other forms might be ado ted and various changes and alterations mae in the shape, size, and proportion of the elements therein withoutdeparting from the spirit and scope of the invention.
